To all wiont'i mag/concern: v

.Be vitknown that i? THOMAS B. FIELD? of Nantucket? in the county ot' rNai'itucitet and State of Massachusetts? have invented anew and Improved Horizontal WindWheel; and l do hereby declare that the following` is a full,

. clear7 and exact description thereof? which -will enable those skilled in the art to malte and use .the same? ret'crencebeing had to the accompanying drawings? formin g apart of this specification? in whichv 4Figure 1 is a plan or top view of my inven' tion; Fig. 2? a vertical central section of the same g Fig. 3? a horizontal section of the saine? taken in the line a@ m? Fig. 2.

Similar letters of reference 'indicate corre-A sponding parts.

This invention relates to a new and iinyproved horizontal wind-wheel of that class in which the wings or sails are turned automatically from an upright to a horizontal position, and vice versa? as the wheel is rotated in a horizontal plane under the-action of the wind.

The abject of the invent-ion isto cbt-aina wind-wheel of the class specified which will operate with certainty and precision? and will.

be capable of turning in either directionthat is to say? either to the right .or left, as may be desired.

A represents a framing', in which an up` right4 shaft?l,is placed vertically and allowed have each four rows of teeth? e, on them? arranged in spiral rows of three teeth each. The shafts D are allowed toturn freely in their bearings, and on each shaft, just inside of the rixn G? there is placed a band? E? provided wi-th four pins? f? at equal, distances apart. These bands E are adjustable circumierentiallyto a certain degree onthc shafts D? and they are secured on said shafts by seta screws g? passing` through slots'h in the bands, the slots h being` of such a length as to admit of a properdegree of adjustment of the bands? which is ahoutthc oneeigh'th ot' a revolution on thc shafts. .The pins f of the-bands E, in

connection with catches hereinafter described, -i are for the p urpose of holding' the shafts D and the wings or sails F, which are attached to them? in proper position during'the inten notched at their outer ends to receive. the pins j', said plates being secured at their inner ends to slides H5 the outer parts of which pass through the rim C, the inner parts being fitted in'the shaft B? cach slide havimg` a spring? b", upon it? which springs have a tendency to keep the notched ends of the catches G over Y the `pins f. (Seo Fig..2.) ly-this arrange@ ment it will ybe secu that in Aorder to allowthc shafts D to turn?the slides H must be pressed the catches G? and these pins, on account of the engage themselves with the catches, so .as to hold the shafts.

per end? g? of the framing Agwhich is of annular form? and is clamped thereto by plates lJ? which are screwed to the under side of the bar I? and bear against the under side ofthe top'of the framing? as shown in'Fig. 2. On the bari? near each end? is fitted a sliding plate? K. These plates work between guides h li on the bar l? and they are moved or adjusted in a direction longitudinally with the l bar 1 by means of levers L; (Shown in Fig. 2.).

These levers are retained in proper position at desired points in their movement by means of pins passing,` through them and through perforations in pendent segmentbars-M, at-. tached to the plate-I.l Eachplate K is provided with three projections, t, on its upper surface? which? when the plates K are adjusted f in a certain position? are in line with the teeth c ofthe shafts D? so that said teeth will come vals 'between their adjustment. rilhe catches G are composed of two elastic plates,.a ax? bacl; in order to disengage the pins f fromy `elasticit-yof the plates ax a??? arc-enabled to l is a bar or plate which is fitted on the udpi' and release the pins f of the bands E, so tha-t the shafts D mayturn when the teeth e come in contact with the projections i on the plates K, the shafts turning just one quarter. of a revolution each time they pass over the plates K. The wings or sails may be constructed in any proper mannerand attached longitudinally and centrally to shafts O, which are selcured in the ends of the shafts D. ,The tnrnf ing of the-'shafts D by means' of the teeth and projecticns t', as described, 'causes the Wings or sails' to turn froma horizontal to a vertical position, and vice versa, the wing or sail on one shaft D being in a vertical. position when the wing or sail on the opposite shaft is in a horizontal position; l-ence it will be seen that the wings or sails at one side of the Wind-Wheel are in a vert-ical Vposition for the wind to act against and rotate the Wheel, the Wings cr sails beingl turnedl down to a horizontal position as their shafts D pass over the plate K at the center of the rear or leewardside of the wheel, and being retained; in such position until they arrive at the center of the front or Windward side of the wheel, at which'point the shafts D pass over the' other plate K and. the Wings or sails are turned up- Ward to a vertical position for the wind to act against. A The wind'whcel may be rendered-inopcra-- 'tive at any time by adjusting theplates so tha-ttheir projections i will be out of line with the teeth e.

l The Wheel may be made to rotate either to the right or left, as desired, by adjusting the bandsv il on the shaftsD, so as to regulate the position of the pins f relatively with the teeth e and cause the wings or sails to'assume a Vertical position at the side of the vWheel where it is designed that the Wind shall act.

I claim as new and desire'to secure by Let ters Iatentfv l. The turning of the Wings or sails from a vertical to a horizontal position, and vice versa, by meansof the teeth e on the shafts v D and the projections t' on the adjustable or' sliding plates K, or the. equivalents of said' teeth and projections, when used Awith the vplates K, to 4operate substantially as and for the purpose set forth.

2. The bands n, provided with tcerhvin .connection with the catches G, attached to the slides l'I for the purpose of retaining or holding the Wingsl or sails during the intervals between their adjustment, substantially as described.v

3. The projections j j at the inner'sides of the plates K, in combination with theslides H, lto which `the catches G are attached, all arran ged, Isubstantially as shown, for releasing the shafts D and admitting ofthe turning ot' the Wings or sails, as set forth.
